7-1. A very large nuclear fusion reactor has an extremely high temperature gas circulating in a torus-shaped cavity. This gas is kept in place partially by a huge magnetic field generated coils of wire wrapped around the cavity. In order for the fusion reactor to work, the magnetic field strength needs to be 3.45 T where the gas orbits down the middle of the cavity, a radius of 2.96 m from the center. The maximum current the wires can stand is 14 kA. (a) How many coils of wire are required to generate the required magnetic field? (b) What force does the magnetic field exert on a proton if it is orbiting at 90% of the speed of light (3.00x108 m/s) but is not deviating from its orbit in the middle of the cavity?
